> The use cases where it gets applied are far more than the valid ones

Yeah, and im seeing the same pattern with AI i think

Genetically engineered, properly “educated”, politically controlled, and brain washed humans would be far more useful than electromechanical robots we can build any time soon. This too is a common scifi trope.

And it’s true. Industries have shown time and again that they’d rather send the work to paupers’ hands in countries without rather than automate to metals hands within.

On Raspberry Pi, the GPU is the only thing that makes a responsive GUI or web-browser feasible, and is the primary reason most people use the HDMI LCD screens for games etc. It also took a large effort to bring up a v4l2 kernel driver for the camera modules etc.

For example, on the CPU one may pin all cores to stream a USB camera or software decode h264. With the SoC GPU decoding or streaming with the v4l2 interface might take up 30% on one core (mainly to handle the network traffic.)

The Raspberry Pi are not the fastest or "best" option (most focus on h264 or MJPEG hardware codecs), but the software/kernel ecosystem provides real value. Also, the foundation doesn't EOL their hardware often, or abandon software support after a single OS release.

A cheap RISC-V SBC is great, but ISA versions are generally so fractured (copied the worst ideas of ARM6)... few OS will likely waste resources targeting a platform that will have 5 variants a year, and proprietary drivers.

A Standard doesn't even need to be good, but must be consistent to succeed. =3

the title says "... AI projects". now, maybe our definitions are different, but you probably want some hardware acceleration.

Enough to maintain your CubeSat's orbit and do a bit of pointing, but you'd need something bigger to have the propellant and power to get out of the solar system

Very very little, but not nothing. I've seen a few tiny deployable solar sails and a few tiny electric motors in my brief research for my video. They seem mostly experimental, to test out theories and miniaturization.

I thought professors loved making students by the latest version of the book they wrote discussing how the wheel was invented

Yeah, I've come to that realization on my own. That's why I spoke in past tense.

Yeah I did the type where you start somewhere inside the maze and have to find the "treasure". Mainly because it was slightly easier to implement, but also had the nice side effect of not being solvable by that rule alone.

FWIW the LLMs were definitely not following that rule. They seemed to always keep going straight whenever that was an option. Which meant they would always get stuck at T intersections when both ways led to a dead end.

Like I said, they can implement the algorithm to solve it, but when forced to maintain the state themselves, either internally or explicitly in the context, they are unable to do so and get lost.

Similarly if you ask to write a Sudoku solver, they have no problem. And if you ask an online model to solve a sudoku, it'll write a sudoku solver in the background and use that to solve it. But (at least the last time I tried, a year ago), if you ask to solve step-by-step using pure reasoning without writing a program, they start spewing out all kinds of nonsense (but humorously cheat: they'll still spit out the correct answer at the end).
